This is a digitised version of the 'How Do I Pass the Redacted.ch interview' pdf guide.
Analogue vs digital
- Needs to be converted from analogue → digital (eg FLAC, MP3) via converter to a file that the PC can read
- Analogue medium: Stores music in an object being physically altered to produce sound
- Examples
- A tape recorder changes the magnetization of magnetic tape in a cassette tape to record sound. Plugging a tape deck into a recording device makes a digital copy of the analog cassette tape.
- A record cutter carves grooves in a vinyl record to make a physical representation of the sound. Ripping vinyl through a preamp and into a sound card makes a digital copy of the analog vinyl
- Allowed
- Vinyl (always)
- Cassette under strict conditions
Digital
- Already encoded as a PC readable format
- Digital medium: object storing music in digital files (a binary number string)
- Examples
- CDs
- DVDs
- Super Audio CDs (SACD)
- WEB store downloads (iTunes, Amazon, etc.)
- Allowed
- after using spectral analysis to check for lossy transcodes
